This will be part of an ongoing series diving into the emerging nuclear energy technologies, to feature heads of the cutting edge startups and some technical and philisophical debates about where the industry needs to head in order to solve the world's energy needs.

The following is from Erik Townsend's Substack (full post) which gives a look into the significance of the milstone achieved:

Full disclosure: I am an early investor in Aalo Atomics and have a direct financial interest in the company's success. Nothing here is investment advice. Early-stage private investments are speculative, illiquid, and can go to zero. Do your own diligence.

At the stroke of midnight on July 4th, 2026, the United States of America began its 250th year. Nineteen minutes later, at 12:19 a.m. Mountain Time, a small nuclear reactor sitting on a two-acre plot at the edge of the Idaho National Laboratory reached criticality — the moment a nuclear chain reaction becomes self-sustaining. Aalo Atomics had just made history.

This post explains why that was historic. But it also makes a bolder claim, so let me put it up front where you can argue with it:

The criticality demonstration that just made headlines is the least important thing Aalo will do. The event that will actually change the course of history is scheduled for the second half of 2027 — and almost nobody is paying attention to it yet.

Bottom line up front:

Four American companies brought first-of-a-kind advanced reactors to criticality in a single month — more genuine reactor firsts than the previous half-century produced. Give them all credit.

Of the four, I contend Aalo's was the most commercially important, for two reasons almost no one is discussing: it was the only one built at full commercial scale, and it uses the one fuel form that doesn't depend on a non-existent supply chain.

The 2026 criticality was a physics demonstration. The 2027 demonstration — the first Aalo-X reactor actually making electricity that powers something substantial — is the starting gun for what I call the Nuclear Henry Ford Moment.

Aalo has a SAFE round closing this month and a Series C now being shopped. I expect the Series C valuation — which some will likely complain is too high — is going to look, in hindsight, like the bargain of the century. I'll show you why using a company you've heard of.
